To all whom it may concern Be it known that I, JAMES WV. SNEDEKER,

a citizen of the United States, and a resiclosely bending the outer portions of the cross wires around the bars of the frame and then fastening the ends of the wires by twisting them around'the main portionsof the wires. i V

This invention consists in the combination of novel means for tightly stretching .parallel wires, novel means for bending the wires around transverse bars, and novel twisters for securing the free ends around the main portions of the wires.

It further consists in the details of construction illustrated in the accompanying drawings and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan of this improved machine, the driving mechanism being omitted for the sake of clearness. Fig. 2 is a rear elevation of the machine. Fig. 3 is an elevation of the left end of the machine. Fig. 4 is a diagrammatic front elevation. Fig. 5 is a plan of the driving mechanism. Figs. 6 to vQinclusive are details of the controlling devices of the driving mechanism. Fig. 10 is an elevation of the frames for supporting the benders and twisters. ,Fig. 11 is a section of a shoe of a bender. Fig. 12 is a plan of the supporting frames for the benders and twisters. Fig. 13 is an elevation from the inside of the machine of one of these frames. Figs. 11, 15 and 16 are views illustrating the action of the benders. Figs. 17 and 18 are details of the bender-s. Fig. 19 is a perspective view of one of the twister gears. Figs. 20 #3023 inclusive are views in dicating the action of the twisters. Fig. 2a is a View of a: completed loop. Fig. 25 is a section of a securing device for the bender frames. V v

Similar reference characters refer to like parts throughout the several views.

Grates which are to be used with wire fences are usually in the form of rectangular frames, sometimes provided with cross bars or other braces, and often formed of tubing with the end bars usually parallel, as are also the top and bottom bars. The wire fabric extending between thebars of the frames is often of the same construction as the fence with which they gate is to be used. In the present case, the wire fabric is the same as that shownin the patent toCornell, Number 1,105,622, dated August eth, 1914-, although any other desired fabric canbe secured in position by means of this machine, so long as it is provided with longitudinal ends which maybe bent around the end bars of the gate frame. Cross or picket wires are not necessary although desirable.

In the operation of this machine, a piece of wirefabric of proper length, consisting of longitudinal wires 1 and preferably of transverse wires 2, is placed in the machine and the extending portions of the wires 1 are engaged by clamps, after which these wires are tensioned. A gate .frame consisting of the endbars 3 and top and bottom bars 4 is then laid on the fabric. The portionsof the wires 1 that extend beyond the bars 3 are then carried to the position shown in Fig. 16 by means of the benders, after which the twisters act on the ends of the wires until the wraps shown in Fig. 2 1 are obtained. j Small loops 5 may be secured by hand between the wires 1 and the bars 4. before! the finished gate is removed from the machine. The twisters are operated by racks thatmove in one direction to turn the twisters and in the opposite direction dur ing the time the finished gate is being removed a'nd before a new frame is placed in position, to return the twisters to normal position. 1 y

The bed of this machine may be made of sufiicient length to accommodate gates of practically every length that may be desired, and consists of I-beams 7connected by cross bars 8. On the upper flanges of the I- beams are secured the racks 9 with which the gears 10 are in mesh. These gearsare secured, in pairs, on the shafts 12, mounted in the upright headstocks 13, which are slidable on the bed when the shafts 12 and gears 10 are turned by means of the cranks 14 to adjust the machine for gates of dif ferent lengths. Gibs 15 can be tightened against the flanges of the I-beams to lock the headstocks in place. I

On the headstocks 13 are the bearings 16 for the shafts 17 on which are secured the eccentrics 18 and the crank handles 19. The

upper ends of the headstocks are formed 7 cross bars 22 on both sides of the eccentrics '18 so that each cross bar will be moved in or out when its shaft is turned. Supporting bars, preferably of telescoping'tubes 24 and 25, maybe mountedon the shafts 17 tosupport the wire fabric.

As indicated in Fig. 1, there is a bender and a twister for each end of each wire 1, the benders and twisters being mounted in small frames firmly secured to the cross bars 22: The cross bar is formed of a vertical plate 26 and an angle plate 27, as shown in Fig. 14. The lower edge of the plate 26 is beveled and engaged by the gib 28 under pressure of the set screw 31 of each frame for each bender and twister. The separate frames are each formed with an outerplate 29 and'an inner portion 30 secured together by screws 33. The inner edge of each frame is formed with an arm- 34 that extends down across the angle. plate 27 of the crossbar, which angle plate is formed with a groove 35 toreceive the gib 36 which has side pieces 37 that connect to the front bar 38 by screws 39. These side pieces are slidable inproper grooves the arm 34. A screw is threaded the arm 34 and engages the gib 36 to force it into engagement with the inclined upper side of the groove 35, and thus, in connection with the screws 33, holds the bender frame in position.

' 'Tke benders.-The front plate 29 of each bender frame is formed with vertical guides 42 between whichthe shoe 43 is vertically 'slidable. A small bar 44 may be held across between the lower ends of these guides by means of a plate 45. On the shoe V are thelugs 46 that carry the pin 47 on which the link 48 is mounted. An inclined projection 49 on this shoe is provided with a groove 50 to receive the wire 1, as hereafter explained. The link 48 is also provided with a groove 52 toreceive the wire.

A screw 53 limits the upwardmovement of the shoe. 'The link 48 carries a pin 54 at its upper end which supports the lever 55 having the claws 56, the handle 57 and the wire-engaging central portion 58, having a groove 59. On this lever is a pin 60 on which' is mounted a latch 61 adapted to engage over the lip 62 on the frame 29 and having a'handle 63 to release it; On the inner portion 30' of the bender frame are two 'abutments 65 and 66, connected at their lower portions and secured in position by means of the screw 67, the abutment 66 having a pocket 68, as shown in Fig. 16, in

which is an eccentric 69, mounted on the shaft 70 that is provided with a squared upper end so that it can be engaged by a proper tool. The elevated parts of the portions 29 and 30 of the bender frame are formed with deep slots 72 to receive the wires 1.

The operation of the parts thus far described is as follows: The fabric being prepared, it is laid on the cross bars 2425 with the ends of the wires 1 lying in the deep grooves 72 and between the abutments 65 and 66. The small shafts 70 are then turned so that the eccentrics 69 may tightly grip the wires. The shafts 17 are then turned by means of the crank handles 19 to the positions shown in Fig. 2, which forces the cross bars 22 outwardly and with them all of the abutments 65 and 66, thus tensioning all the wires 1. The gate frame is now laid on the fabric with the end bars 3 outside of the cross bars 22. A handle 57 of a bender at the end of a row is then swung up by the operator of the machine. If two men are employed, one may work at each end, starting with the bender at either end of the row. At the beginning, the parts will be as seen in Fig. 14, with the wires 1 between the claws 56 and the tube 3 resting on the wires. The handle 57 is then swung up until the ends of the claws 56 rest on the tube 3, the part 58 of the lever engaging the wire and beginning to bend it. At the same time, the shoe 43 is beginning to move up. This brings the parts to the positions shown in solid lines in Fig. 15. Further movement of the lever 55 carries the shoe 43 into engagement with the screw 53 and then forces down the tube 3, as indicated by dotted lines in Fig. 15. When the lever 55 has reached the position shown in Fig. 16, the tube 3 will havebeen forced down so low that the loop of wire around it will lie in the groove 50 in the projection 49 on the shoe, and the link 48 will have been pulled in so that the wire 1 lies in the groove 52 in this link. The downward position of the tube 3 is limited by the fingers 64 projecting from the front plates 29. At the same time, the intermediate portion 58 of the lever will have brought the end of the wire down until it is substantially parallel to or in engagement with the main portion, and the latch 61 will have engaged over the lip 62. The benders are all brought to this position, after which the twisters are set in motion. As the shoes 43 are in engagement with the screws 53, the bar 3 is in engagement with the fingers 64, the levers 55 are in engagement with the top of the bar 3, the bar 3 cannot possibly move and the ends of the wires can be wrapped around the main portions of the wires.

The twisters.Mounted in bearings formed in the outer portion 29 and inner portion 30 of each bender frame is a small gear 7 6 having journal hubs 7 Elm each end, as shown in Fig. 19. The gear is hollow and has a slot-7 4 to permit the return end of the wire 1 to be bent down, the slot 74 always being upright during the operation of the bender, as shown in Figs. 10 and 16. In the counterbored outer hubof the gear is mounted a twisting die 7 5, secured in position in any desired manner, screws preferred. This die is somewhat more than three-fourths of a circle, as shown in Fig. 19, with a central hole that is enlarged at its outer end. One wall 77 is formed with a groove 78 to receive the end of the wire.1 as it is being twisted around the main portion of wire. After the benders have all been operated to bring the ends of the wires 1 to the position shown in Fig. 16, the gears are turned by moving the rack bar 79 away from the observer in that figure, thus turning the gears and their dies 75 as shown in Figs. 20 to 23. The first one-third revolu tion will bend the ends of the wires to the positions shown in Figs. 20 and 22. The first full revolution results as indicated in Figs. 21 and 23, the end of the wires being in the groove 78, while a second complete revolution leaves the wires as shown in Fig. 24, free from the walls of the twisting dies. The parts are so proportioned that these gears will make at least two full revolutions and stop with their slots 7 4 upright so that the wires 1 can be lifted out after being secured to the gate frame. The two rack bars 79 are reciprocated together to turn the gears 76. Each is mounted on a plurality of shoes 82 which are slidable between the parts 26 and 27 of-the cross bars 22, as shown in Figs. 3 and 16. On each shoe 82 at the front of the machine is mounted a pin 83 that connects to the pitman 84, whose :ear end connects to the pin 85 carried by the cross link 86, which, in turn, is mounted on the crank pin 87, adjustably mounted in the slot 88 in the crank disk 89 secured to the shaft 90. This shaft is mounted in bearings 91 in its headstock 13. Means are provided for turning this shaft one-half revolu tion from the position shown in Fig. 3 so as to give the gears 76 two full turns through the operation of the rack bar 79 and then to hold the parts from movement until the finished gate is removed, after which the crank disk 89 is given another half-revolution to move the rack bar and gears to starting position.

The driving me07mnism.Secured to each of the shafts is a gear 93 which meshes with the gear 94, slidable upon but revoluble with the main shaft 95. The gear 93 is provided with a well known stop plate 96 which is engaged by the segment 97 con nected to the gear 94., the gears being so proportioned that the shaft 90 will make one-half-revolution during about two-thirds of a revolutionof the shaft and remain at rest during the other third of a revolution. This shaft 95 is mounted in bearings 98 carried by brackets 99 and 100. Secured to the shaft 95 is the gear 102, and on this shaft are revolubly mounted the pinions 103 and 105 and the gears 104 and 106. The pinion 103 is connected to the gear 104 while the pinion 105is connected to the gear 106. On this shaft is also secured the disk 107. A shaft 108 is mounted in bearings 109 also carried by the brackets and on it is secured the disk 112 and the pinion 113 which meshes with the gear 106. Loose on the shaft 108 are the gears 114 and 116 and the pinions 115 and 117. The gear 114 is connected to the pinion 115 and the gear 116 with the pinion 117. In this manner a very powerful driving gearing is obtained to drive the shaft 95 at low speed. A pulley 119 is loose on theshaft 108 and has several laterally projecting pins 120. .See Figs. 5 to 9 inclusive. A crank arm122 is secured to the shaft 108 adjacent the disk 112 and a pin 123 is mounted in the outer end of this arm. 124, a dog 125, and an arm 126 that connects to a spring 127 which extends from the pin 128 and normally swings the pawl 124 out into the path of the pins 120 on the pulley. The face of the disk 112 has a depression 129 to receive the pin 128, spring 127, arm 126 and dog 125, as well as a portion of the arm 122. Loosely mounted on the shaft 95 is a plate 131, having an arm 132 whose outer end normally rides on the periphery of the disk 112. But when the depression 129 reaches this arm, the end thereof may move into the path ofthe dog 125, stopping it, together with the crank.

arm 122 and shaft 108, at the same time swinging the pawl 124 inwardly out of the path of the pins 120. The means for lifting this arm 132 out of engagement with the dog 125 to permit the spring 127 to swing the pawl 124 into the path of these pins 120 is as follows. See Figs 2 and 4 to 9 inclusive. A pin 134 is carried by a headstock 13 or any other desired part of the machine, and on it is mounted a lever 135, whose lower end engages a pin 136 on a sleeve 137, adjust-ably mounted on the rod 138. This rod connects to a pin 139 on the arm 140 of a bell-crank, mounted on the pin 142 on the bed 7. The other arm 143 carries a pin 144 to which connects the lower end of a rod 1.45 that connects to the arm 146 also connected to the plate 131 and practically in line with the arm 132. On the arm 146 is a triangular ridge 147 that engages with the V-shaped detent at the upper end of the spring 148, carried by the bracket 149 on the bed 7. When this arm 146 is swung up or down, the ridge 147 is forced past this detent, which, in turn, prevents On this pin is mounted a pawl.

and 146, which grooves are made use of.

merely to render the construction more compact. Projecting from the arm 146 (to the right in Figs. 2 and 5), are two lugs 154 that carryv the pin 155 on which the -'lever 156 is mounted. One end of this lever extends into the groove 152, as indicated in V Fig. '9, and'the other rests on the adjustable post 158,. mounted on the bracket 159, as shown in Figs. 2, 5, 7 and 8. -lVhen the disk 107 and the shaft are completing one revolution, afterthe shaft 90 has completed one half-revolution, the' pin 151 passes up through the groove 152 and engages the adjacent end of the lever 156, raising it. As the support 158 is a fulcrum of this lever, thepin 155 will be lifted by the pin 151 and with it, the arm 146. This causes the arm 132 to'be depressed into the recess 129 in the disk 1'12, and into the path of the dog' 125, and also causes the pawl 124 to ,be swung out of, the path of the pins 120,

and therefore causes the machine to stop; It is evident that as this stopping occurs when the pin 151 has reached a certain predetermined position with respect to the arm 146, that the rack-bars 7 9 will stop at both ends of their strokes, and always at the same places,- thus insuring the stoppage of the gears 76 with their slots 74 vertical.

Many changes can bemade in the details of construction'of this machine without departing from the spirit of 'my inventions Thus any other desired drivingmechanism may be employed so long'as it Wlll move the rack-bars through exactly one full stroke and then'hold them in such positions until it is desired that they shall make the next stroke. In fact, any other desired mechanism'may-be employed to turn the twisters the proper number of full turns in one direction, and then, after the desired interval, turn them backagain to starting position.

When it is desired to adapt this machine for fabrics whose longitudinal wires are spaced farther apart than shown in Fig. 1, the screws 31 and 40 are withdrawn and the gibs 28 removed, which permits the bender frames to be lifted sufficiently to disengage the teeth of the gears 76 from those of the rack bars 79. The bender frames are then shifted to the desired positions, but the distances thatthey are moved must always be a multiple of the pitch of these teeth in order that the slots in the gears 7 6 maylower ends of the links 48 and to the cross' bars 164 as indicated in Fig. 2.

While it may be desirable to cut the fabric in proper lengths previous to bringing it to this machine, a frame 165, shown in Fig. 4, may be employed to support the shaft 166 on which the roll 167 of the fabric is wound. This fabric may'then pass over a roller at the top of the frame andthence to the machine, a guide 168 being provided to permit the operators to cut the wires 1 to exactly the desired length.

In tightening the eccentrics 69 onto the wires 1, they should be turned to the left (in Fig. 12), so that, when they are moved outwardly by means of the crank handles 19,'

the pull of the wires 1 will serve to tighten them still more. After the twisters have operated, the benders areswung down to original position, and the cross bars and bender frames moved back. The resulting inward pressure on the wires 1 will result in' the eccentrics being turned to the right, thus releasing the wires 1.
